I am building a new home and they are ready to pour the concrete patio. I have mixed messages about whether the patio should be pinned to the foundation to avoid cracking/settling. We live in NE so the weather brings freeze/thaw. A deck is above the patio and sits on 3 ft deep footings. The concrete patio will be over those footings as well. Should we pin the patio to the foundation or will that cause more cracking than leaving it alone?
